Hypertensive effects of the iv administration of picomoles of ouabain
Brazilian Journal of Medical and Biological Research, 2011 Ouabain, an endogenous digitalis compound, has been detected in nanomolar concentrations in the plasma of several mammals and is associated with the development of hypertension. In addition, plasma ouabain is increased in several hypertension models, and

Effect of ouabain on calcium signaling in rodent brain: A systematic review of in vitro studies
Frontiers in Pharmacology, 2022 The Na+/K+-ATPase is an integral membrane ion pump, essential to maintaining osmotic balance in cells in the presence of cardiotonic steroids; more specifically, ouabain can be an endogenous modulator of the Na+/K+-ATPase. Here, we conducted a systematic

The Influence of Ouabain on Human Dendritic Cells Maturation
Mediators of Inflammation, 2014 Although known as a Na,K-ATPase inhibitor, several other cellular and systemic actions have been ascribed to the steroid Ouabain (Oua). Particularly in the immune system, our group showed that Ouabain acts on decreasing lymphocyte proliferation ...

Consequences of the Lack of TNFR1 in Ouabain Response in the Hippocampus of C57BL/6J Mice
Biomedicines, 2022 Ouabain is a cardiac glycoside that has a protective effect against neuroinflammation at low doses through Na+/K+-ATPase signaling and that can activate tumor necrosis factor (TNF) in the brain.

Changes in extracellular pH during electrical stimulation of isolated rat vagus nerve [PDF]
, 1986 Double-barrelled pH-sensitive micro-electrodes were used to record changes of extracellular pH during repetitive stimulation of isolated rat vagus nerves. It was found that a small initial alkaline shift was followed by a prolonged acidification.

Ouabain and Serum Sodium [PDF]
Hypertension, 2005 To the Editor: Sodium-dependent mechanisms play a role in the pathogenesis of hypertension. He et al recently demonstrated that in normotensive and hypertensive subjects an acute reduction in salt intake, from 350 to 10 mmol/d for 5 days, was associated with a decline in serum sodium by ≈3 mmol/L.1 Conversely, a progressive increase in salt intake ...

Ouabain, a cardiac glycoside, inhibits the Fanconi anemia/BRCA pathway activated by DNA interstrand cross-linking agents. [PDF]
PLoS ONE, 2013 Modulation of the DNA repair pathway is an emerging target for the development of anticancer drugs. DNA interstrand cross-links (ICLs), one of the most severe forms of DNA damage caused by anticancer drugs such as cisplatin and mitomycin C (MMC ...

Cellular mechanisms of potassium homeostasis in the mammalian nervous system [PDF]
, 1987 Double-barrelled ion-sensitive microelectrodes were used to measure changes in the intracellular activities of K+, Na+, and Cl- (aKi, aNai, aCli) in neurones of rat sympathetic ganglia and in glial cells of slices from guinea-pig olfactory cortex.

Anti-inflammatory and Antinociceptive Activity of Ouabain in Mice
Mediators of Inflammation, 2011 Ouabain, an inhibitor of the Na+/K+-ATPase pump, was identified as an endogenous substance of human plasma. Ouabain has been studied for its ability to interfere with various regulatory mechanisms. Despite the studies portraying the ability of ouabain to
